Description

A decoupling dissipative fluid emits particles differently from an ideal one. The modification can be estimated with the help of a saddle-point calculation, which amounts to the limit of a low freeze-out temperature. Computing the anisotropic flow coefficients, we show that relations between different harmonics valid in the ideal case for particles with a higher velocity than the fluid no longer hold. This may be exploited to actually constrain the functional shape of the dissipative corrections, and thereby the transport coefficients of the fluid at freeze out.
